%description
Charliecloud uses Linux user namespaces to run containers with no privileged
operations or daemons and minimal configuration changes on center resources.
This simple approach avoids most security risks while maintaining access to
the performance and functionality already on offer.

Container images can be built using Docker or anything else that can generate
a standard Linux filesystem tree.

# The version of sphinx-build on epel is old; to build the docs we must perform

# 0. patch doc-src/conf.py to find sphinx_rtd_theme
# 1. edit Makefile to not treat warnings as errors;
# 2. remove the 'widths: auto' syntax from doc-src/install.rst;
# 3. remove the 'dedent: 0' syntax from doc-src/dev.rst; and
# 4. comment out the minimum sphinx-version doc-src/from conf.py

For RHEL7 you must increase the number of available user namespaces to a non-
zero number (note the number below is taken from the default for RHEL8):

  echo user.max_user_namespaces=3171 >/etc/sysctl.d/51-userns.conf
  reboot

Note for versions below RHEL7.6, you will also need to enable user namespaces:

  grubby --args=namespace.unpriv_enable=1 --update-kernel=ALL
  reboot
